WARNING!

On current transformers that are operated open
on the secondary side,
high voltage peaks that are dangerous to touch
can occur, which can cause severe bodily injuries
or death.

Therefore, note the following:

• Avoid operating the current transformers
open.

• Short circuit all unloaded current
transformers.

• Connect the earthing connections provided
on the current transformer to the earth.

• You must short circuit the secondary
connections on the current transformer
before interrupting the power supply.

• If a test switch, which automatically short­circuits the secondary wires of the current
transformer is available, it is sufficient to
set this to the "Test" position as long as the
short-circuiting device has been checked
beforehand.

• Ensure that the attached screw-type
terminal is affixed to the device sufficiently
using the two screws.

• Safe open-circuit current transformers are
also dangerous to touch when they are
operated open.

6. 4. 3 Direct measurement

Rated currents of up to 5 A can be measured
directly on the device. When doing so, note
that each current measurement input can be
continuously loaded with 6 A or loaded with
max. 100 A for 1 second.

The device does not have integrated
protection for current measurement.
Therefore, provide a 6 A line protection fuse
or automatic circuit breaker as protection
against overcurrent when installing.

6. 4. 2 Total current measurement

For a summation measurement via
two current transformers, first set their
total transformation ratio on the device.
For information on setting the current
transformer ratios, see “11. 1 Current
transformer ratio”.

Example:

The current is measured via two current
transformers. Both current transformers
have a transformation ratio of 1000 / 5 A.
The summation measurement is performed
using a 5+5 / 5 A total current transformer.

The device must then be set up as follows:

Primary current: 1000 A + 1000 A = 2000 A
Secondary current: 5 A

7. 4 Bus structure

• All devices are connected in a bus
structure (line).

• Up to 32 participants can be connected
together in a single segment.

• The cable is terminated with resistors at
the beginning and at the end of a segment.

• If there are more than 32 participants,
repeaters (amplifiers) must be used to
connect the individual segments.

• Devices for which the bus connection is
switched on must be under current.

• It is recommended that the master be
placed at the end of a segment.

UMG 604-PRO

• If the master is replaced with a bus
connection, the bus must be switched off.

• Replacing a slave with a bus connection
that is either switched off or de-energised
can destabilise the bus.

• Devices that are not connected to the bus
can be replaced without destabilising the
bus.

9. Commissioning

Before commissioning, clear any content
that may be present on the power meters,
min./max. values or recordings due to the
production process.

9. 1 Connecting the supply voltage

After connecting the supply voltage, the
text “Start up” is shown on the display.
Approximately two to six seconds later, the
device switches to the first measured value
indication.

If no display appears, check whether the
power supply voltage is within the rated
voltage range.

Supply voltage

(see rating plate)

9. 3 Connecting the measured voltage

The device is suitable for measuring voltages
of up to 300VAC to earth and 520 V AC
phase to phase.
The device is not suitable for measuring DC
voltage. Voltages over 300 V AC to earth
must be connected via voltage transformers.

After connecting the measured voltages, the
measured values displayed by the device for
the L-N and L-L voltages must correspond to
those on the voltage measurement input.

If a voltage transformer factor is
programmed, it must be taken into
consideration for the comparison.
At least one phase (L) and the neutral
conductor (N) must be connected to the
voltage measurement input for measurement.

A measured voltage of greater than 10
Veff must be present on at least one of the
voltage measurement inputs so that the
device can determine the mains frequency.

Fig.23.1 Example connection for the supply voltage Uh.

9. 2 Frequency measurement

In order to measure the frequency, at least one
voltage measurement path (L-N) must have
a measured voltage of greater than 10 V.
Only detected frequencies in the range of
45 Hz to 65 Hz are used for measurement on
the current and voltage measurement inputs.

L N

9. 4 Phase sequence

Check the direction of the rotating field
voltage in the measured value indication
of the device. A “right-hand” rotation field
usually exists.

www.janitza.de

UMG 604-PRO

9. 5 Applying the measured current

The device:

• is intended for connecting current
transformers with secondary currents of
../1 A and ../5 A.

• does not measure DC.

• has current measurement inputs that are
continuously loaded with 6 A or loaded
with 100 A for 1 second.

Proceed as follows to connect measured
current to the device:

1. Connect the currents to be measured to
voltage measurement inputs I1 to I4.

2. Short circuit all current transformer outputs
except for one.

3. Compare the currents displayed by the
device with the applied current.

• Bearing in mind the current transformer
conversion ratio, the current displayed by
the device must correspond to the current
input.

• The device must display approx. zero
amperes in the short circuited current
measurement inputs.

9. 6 Checking the power measurement

Short-circuit all current transformer outputs
except for one and check the displayed
power outputs.

The device may only display one power
output in the phase with a non-short-circuited
current transformer input. If this is not the
case, check the connection of the measured
voltage and the measuring-circuit current.

If the power figure is correct but the power
sign is negative, connections S1(k) and S2(l)
on the current transformer may be mixed up
or they are supplying active energy back to
the network.

The current transformer ratio is factory-set
to 5/5A and must be adapted to the current
transformer used if necessary.

11. 7 Ethernet configuration
Static IP address

In simple networks with no DHCP server, the
network address must be set right on the device
itself.

BootP

BootP enables the device to be integrated into
an existing network fully automatically. However,
BootP is an older protocol and does not provide
the scope of functions provided by DHCP.

DHCP mode

DHCP makes it possible integrate a UMG
604-PRO into an existing network fully
automatically without the need for any additional
configuration. When started, the device
automatically obtains the IP address, the subnet
mask and the gateway from the DHCP server.
The device is factory-set to the DHCP client.
